In Blood Rites, Arturo Genosa told Harry that she's the star of his current film despite being his ex-wife due to contractual obligations. Arturo does not think Trixie is involved with killing the people around him.[3] Trixie make a flashy, over-bearing and late entrance on the film set, making all kinds of demands. She's upset at Arturo for hiring Lara Romany to replace Giselle. When Lara entered, Harry got the sense that Trixie was afraid of her.[4]

Trixie held a gun to Harry Dresden to keep him from stopping the entropy curse, the Malocchio, that is about to land on Emma, targeted there at the studio. Trixie told Harry that she broke the Sacred Circle that he set up with Jake Guffie. Harry tried to get free to stop the curse on time, but Trixie's gun went off while shooting at Harry and two shots go through the door hitting Emma exactly as though it was a professional hit. Harry has to run because Trixie will point the finger at him.[5] That backfired because she refused to ever get his name right.[2]

She is in the Deeps with Madge Shelly and Lord Raith. She claims part credit for helping to sacrifice Lucille Delarossa, the second of the ex-wives. Madge slapps her then zaps her with some spell that gags her. Then Lord Raith heaves her into the deep chasm that the Raiths use for disposing of bodies. She can't scream to her death.[6]
